Erase you from [my heart]", admitting an attraction to Arturo. He says that he will continue to follow her "even into a desert" while she responds: "Your wish will prove your undoing". Then the sound of huntsmen is heard in the distance. Alaide urgently urges Arturo to leave. In the scene finale duet, the couple each expresses his or her feelings and anxieties, hers being to continue to warn him, his being to insist that "your fate will be mine / In life or in death".

Un dubbio atroce / Mi rimane e il cor mi preme... / "Whatever am I to think? My heart is heavy / and I am left with an atrocious doubt..."). When Osburgo and his entourage enter, they tell him that he is betrayed because they have overheard Valdeburgo and Alaide planning to flee together.
